Sound quality is very low.


is awesome!
Hello everyone!
Since the last update I noticed that the sound quality of my bot seems to be much worse than before. It basically feels like listening to a song in 240P from YouTube.
It's not easy to tell, but if you have a good audio card you will notice the difference.
Since I had a couple of problems with Youtube-DL I thought it was an issue related to the quality of the music file itself, so I tried to update a high bitrate .mp3 file but the problem persisted.
My dedicated server has around 1 Gigabit download and upload speed, a really good CPU and enough RAM to run the bot without any issue. I'm also using Opus Music (10) on each channel of my server.
It's really frustrating because I used to listen to a lot of music from the bot, as the quality was really great and had no difference from a high bitrate YouTube song.
Any advice?

There have been changes to the ytdl interface that _might_ cause your issue. But:

Since I had a couple of problems with Youtube-DL I thought it was an issue related to the quality of the music file itself, so I tried to update a high bitrate .mp3 file but the problem persisted.
What exactly did you do?


is awesome!
I apologise for the late reply.
First I downloaded a couple of songs with Sinusbot (using both !yt and !ytdl for the "quality test"), then I uploaded an .mp3 file through the web panel so the file would maintain its quality, without any compression whatsoever. Sadly, I noticed no difference. They both sounded rather bad.

So that means Youtube-DL is not the issue, because the uploaded file would have sounded better than the downloaded file if that was the case.
Clearly, a 320Kbps mp3 file is very different if listened locally or streamed through a VoIP service like TS3 or Discord. But I would expect little difference in terms of quality from listening to a song from YT and downloading / streaming it through the bot.
So it may be something related to Sinusbot or Teamspeak3 itself.

I understand Teamspeak has a pretty low bitrate (only up to 12 Kb/s using Opus Music 10, correct me if I'm wrong) but the quality has changed a lot since last 2-3 updates. It used to be much better, to the point where I'd rather listen to music from the bot than Youtube or my PC.
I also understand that such a problem would be hard to notice or reproduce, and might look like a minor issue, but it's been one of the reasons I stopped using Sinusbot for "daily music listening".

I also noticed this lowering of quality. It sounds really bad in songs with not many high notes.
I think I noticed it first with the first update that supported TS 3.1

It's very Low Quality with Radio stations (Music Streams) too.
Definitely not something related to Youtube-dl
The same for me, I've uploaded mp3 320kpbs files which sound great using for example winamp. Playing with sinusbot you hear a kind of hiss in the background. Even more with Opus Music Quality 10 channel codec.
